Ornate Fountain

Taken all the way down to base materials, one Ornate Fountain is 3 crafting steps deep and needs 4 intermediates — Bluespirit Tile ×4, Mahogany Lumber ×3, Mortar ×3 and 1 other — which resolve to 7 distinct raw materials totalling 49 units, plus 65 crystals.

That bill outweighs 12,749 of the 13,602 recipes tracked here and 2,059 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 16 of those crystals go into the final step; the other 49 are burned by the intermediates, so the real crystal cost is 36 Fire Crystal, 15 Wind Shard, 8 Wind Crystal and 1 other kind.

The chain crosses four disciplines — Goldsmith to Lv 90, Blacksmith to Lv 74, Carpenter to Lv 39 and Alchemist to Lv 20 — so no single class can finish it unaided.

All 7 raw materials are gathered, and not one of their spots is timed, so nothing in the tree waits on the Eorzean clock.

Of the intermediates, Mortar has the widest use: 140 recipes call for it, spanning six of the eight crafting classes.
